scvi 0.5.0

Single-cell Variational Inference

scVI

Single-cell Variational Inference

• Free software: MIT license

• Documentation: https://scvi.readthedocs.io.

Quick Start

1. Install Python 3.7. We typically use the Miniconda Python distribution and Linux.

2. Install PyTorch. If you have an Nvidia GPU, be sure to install a version of PyTorch that supports it – scVI runs much faster with a discrete GPU.

3. Install scVI through conda:

   conda install scvi -c bioconda -c conda-forge

   Alternatively, you may try pip (pip install scvi), or you may clone this repository and run python setup.py install.

4. If you wish to use multiple GPUs for hyperparameter tuning, install MongoDb.

5. Follow along with our Jupyter notebooks to quickly get familiar with scVI!

   1. Getting started:

      • data loading

      • basic usage (scVI)

   2. Analyzing several datasets:

      • harmonization (scVI)

      • annotation (scANVI)

   3. Advanced topics:

      • interaction with scanpy

      • linear decoder for gene interpretation (LDVAE)

      • imputation of unobserved gene expression (gimVI)

      • automated hyperparameter search

      • joint model for CITE-seq data (totalVI)

      • detection of zero-inflated genes (AutoZI)
